Figured I would post this here cause there seems to be more knowledgable people here when it comes to the TBI mods. So please help me Figure this out?

Its my 94 5.7 TBI truck. Mods before TBI work 3:73 gears, 4l60e trans with vette servo, shorty headers and electric fans.

I did the ultimate TBI mods today, trans dapt 1" TBi spacer and the 1/4" injector pod spacer.

Exact rundown of what I did to TBI, removed ridges, radiused bores and cut down throttle blade shaft by 50%. Added TBI spacer and injector pod spacer. I used INj pod gasket on both sides of spacer. Removed the breather spacer too.

My truck had no issues before this, now at low speed (basicly idle in gear)when I give it 1/4 throttle or more it hesitates and almost dies then picks up. Too much throttle and it dies. Does not do it in park or reverse or when I punch it at highway speeds. No check engine light or anything else. Truck pulls much much harder now too and I can tell a huge difference in throttle response.... Truck idles better and starts quicker too..

I didnt readjust timing or tps and reinstalled IAC as the same when I pulled it out.

Thanks.
